Digital LCD Power Supply Tester

The Vszerda Digital LCD Power Supply Tester Model IV checks ATX, BTX and ITX desktop or server power supplies. It connects to 20 + 4 pin, 8 pin CPU, and SATA connectors to display voltage status on an integrated LCD. No batteries are required for operation.

Compatibility Check Before Ordering

Verify that the power supply under test uses standard 20 + 4 pin main, 8 pin CPU and SATA power connectors. The unit draws operating power directly from the supply being tested, so no external source is needed. Ensure the supply can be powered at 220v input for the test to function.

Upgrade From Basic Testers

This replaces simple pass/fail testers or multimeters by showing real-time voltage readings for +3.3V, +5V, +VSB, -5V, -12V and +12V rails on the LCD. The jump is worth it when you need immediate visibility of each rail without probing individual pins manually.

Questions about this item

Does the tester ship with every cable needed to check a 24-pin ATX, an 8-pin CPU and a SATA drive, or must I buy extra adapters?

The unit includes the 20+4-pin main connector, an 8-pin CPU plug and a SATA socket, so all listed interfaces can be tested without extra parts.

The box lists Model IV only — are there other capacity or version choices I should consider?

Model IV is the sole version offered; there are no alternate capacities or revisions to select from.

When the LCD shows +12 V, +5 V and +3.3 V rails, what does that tell me about the supply under load?

It confirms each rail is present and within tolerance at idle, letting you spot a dead or grossly out-of-spec unit before it damages components.
